Windows NT TCP/IP Network Administration

Appendix A. PPP Scripting Languages

PPP installation and configuration are described in the Using Dial-up Networking (DUN) section of Chapter 10. A Microsoft DUN client can connect to a RAS server with no additional configuration. But some PPP servers require special logon commands from the client. These commands can be entered manually during each logon or automatically from a logon script. How the DUN client handles the logon process is configured through the Script tab.

If the “Pop up a terminal window” option is selected, a terminal window opens after the local modem has successfully connected to the remote modem. Enter the PPP logon commands required by the remote server through this window. Entering logon procedures through the terminal window allows you to debug the connection before you add the complication of debugging a logon script. The biggest problems with setting up PPP are the modem configuration, which is covered in Chapter 10, and the logon script, which is covered in this appendix. Don’t try to debug both at once.

Using the terminal window to make your PPP connection shows you exactly what commands should be programmed into the logon script. This appendix explains the scripting languages used to place those commands into a logon script.

Creating Logon Scripts

The logon sequence of the remote PPP server can be automated with a script. Windows NT provides two scripting languages for that purpose. We cover both. One is a full-featured language that includes commands ...
